Build your plan around the quieter months, too.
The essentials
When income changes from month to month, an average can hide cash-flow pressure. Separate essential expenses from optional spending and look at the lowest realistic income periods. Keep track of when invoices or wages are expected, not just the total amount earned.
Put it into practice
Use higher-income months to prepare for slower ones before increasing regular commitments. Keep money for taxes or business expenses separate where relevant, using qualified advice for the amount. Review the plan often and give each transfer a clear purpose. A simple calendar of due dates can prevent a timing problem from becoming a missed payment.
Before you decide
Use this guide as a starting point for your own questions. Check the current terms in your documents and the rules where you live. Keep a short written record of the options you compare, the details you still need, and your next step.
